I have to admit that almost three years ago now I ate at Johnny Rocket's several times, since I was missing a good burger and it was great, but for 4 of us to have burgers and shakes, with 2 fries, it was almost 60 bucks. Crazy!
Now if I'm craving some good old fashioned American Crap Food, I just go to Burger King or McDonald's, which are still pricier than in the US, but nothing like Johnny Rocket's.
And good ice cream is hard to get here, I mean really good ice cream like HD, so if I absolutely have to have some, I buy a pint from the grocery store. Still costs almost 10 bucks, but at times it's money well spent, and keeps me from tearing off heads.
